Description
Technical Field

[0002] In existing technology, a water turbine is a power machine that converts the energy of water flow into rotational mechanical energy. It belongs to the category of turbine machinery within fluid machinery. As early as around 100 BC, the prototype of the water turbine—the water wheel—appeared in China, used for irrigation and driving grain processing equipment. Modern water turbines are mostly installed in hydropower stations to drive generators. In a hydropower station, water from an upstream reservoir is directed through a water diversion pipe to the turbine, rotating the turbine runner and driving the generator to generate electricity. The water that has completed its work is discharged downstream through a tailwater pipe. The higher the head and the greater the flow rate, the greater the turbine's output power. The impeller is a key component of a water turbine and typically consists of a runner body and blades.
[0003] During the production process of the impeller, it is usually necessary to install and fix the processed rotor body and the blades, that is, to fix the blades on the rotor body. The through hole on the rotor body is provided with inclined rotor blade mounting holes on its side wall, and a fixing hole is usually provided at the bottom. When installing the rotor blades and the rotor body, it is necessary to place the bottom of the rotor body at an angle to ensure that the mounting holes of the rotor blades on the side wall of the rotor body are set upward to facilitate the installation of the rotor blades. The existing rotor body oblique fixing device is not able to fix the rotor body firmly when fixing the rotor body, and is inconvenient to disassemble, which affects the production efficiency of the impeller. At the same time, the fixing method is difficult to self-lock. Utility Model Content
